The second iPhone update was released earlier this week, officially released for undescribed “bug fixes”. There have been reports that the 1.0.2 update improves scrolling in Safari and that it may even boost the phone’s WiFi reception. The update reportedly uses a validation process to wipe out hacked versions which forces hacked phones to get a fresh install. I don’t expect that will be slowing our iPhone hacker friends down much, though.
Let us know in the comments if you’ve upgraded and seen any change in your WiFi reception, or other interesting side effects from performing the upgrade.
